These components may be further separated or further integrated than the exemplary layout shown in the drawings. The image receiver 310 receives image information and preferably includes a vehicle camera image receiver 311 and a terminal camera image receiver 312. The vehicle camera image receiver 311 receives image information captured by a camera provided to the vehicle from the vehicle. The terminal camera image receiver 312 receives image information captured by cameras provided to the terminal. The terminal camera image receiver 312 includes a front camera image receiver 313 for obtaining image information captured by a front camera 315, and a rear camera image receiver 314 for obtaining image information captured by a rear camera 316. The rear camera 316 keeps “eyes” on the front of a vehicle, that is, a road of the driving direction.

A person of ordinary skill in the art viewing the terminal in FIG. 1 will appreciate that camera 15-1 is positioned similarly to front camera 315 and camera 15-2 is positioned similarly to rear camera 316. In other words, the “rear camera” is in the rear of the terminal 10, and when in the vehicle, would capture in its intended position, would capture images in front of the vehicle, whereas front camera 315 would capture images of the driver or rear of the vehicle. Thus, if the terminal is positioned, for example, on the top of the dashboard, the rear camera 316 would obtain images of the front of the road, similar to rear camera 15-2 (shown in FIG. 1) which is actually located in the back of the terminal 10, which is why it is not shown and represented by dashed lines. The front camera 315 observes a driver's view of a vehicle, and could be positioned, for example, similar to front camera 15-1 shown in FIG. 1, at least in terms of front versus rear.

The sensor receiver 320 receives information detected by various sensors, and includes a vehicle sensor receiver 321 and a terminal sensor receiver 322. The vehicle sensor receiver 321 receives information detected by a sensor (for example, a distance sensor) provided to the vehicle from the vehicle. The terminal sensor receiver 322 obtains information detected by sensors provided to the terminal. Known sensors provided to the terminal may be an acceleration sensor 323, a gyro sensor 324, a GPS sensor 326, etc. More particularly, position information provided from the GPS sensor 326 is used for detecting a point of a road corresponding to the position of the terminal, and thus, the position of the vehicle.

The vehicle operation information receiver 330 communicates with a vehicle wirelessly or via a wired line, and receives information regarding a vehicle operation from the vehicle. The vehicle operation may be flickering of left/right directional light, steering of a steering wheel, on/off of a break, etc.

The traffic information receiver 340 receives information regarding a factor having an influence on traffic at the point of the road detected using the position information via at least one network. More particularly, the traffic information receiver 340 may receive traffic information for each road, including the road currently being traveled on and adjacent roads or roads that recommended by navigation to arrive at one's desired destination. The factor having an influence on the traffic may be a traffic circumstance for each road section, an accident, a construction, etc.

The output unit 350 preferably includes an image output unit 351, typically a display) for outputting image data and a voice output unit 352 for outputting voice data.

The storage 360 stores map data for providing a recommended path for travel, a predetermined program for controlling an overall operation, and various data input/output when a control operation is performed.

The eyeball tracking unit 370 tracks a user's eye(s) while viewing a screen from an image provided from the front camera image receiver 313 of the image receiver 310, and informs the controller 380 of the position of the user's eye(s) being tracked.

The controller 380, which comprises a processor or microprocessor configured to control an overall operation of the terminal, and includes a path generator 381, a road capture unit 382, a virtual road generator 383, a traffic information indicator generator 384, a surrounding information indicator generator 385, and a voice generator 386.

The path generator 381 generates a path from map data of the storage 360 and outputs the generated path to the output unit 350.

With continued reference to FIG. 3, the position determining unit 382 receives position information from the terminal sensor receiver 322 to detect a point of a road corresponding to the position information.

The road capture unit 383 recognizes a road represented on a road image of the front of a vehicle provided from the rear camera image receiver 314, and detects a road as well as the particular lane corresponding to the position of the vehicle having the terminal. The road capture unit 383 may recognize a road and identify the lane by analyzing a road image of the front of the vehicle via an image analysis method such as an intelligence analysis method, a two dimensional binary method, etc.

The virtual road generator 384 generates a virtual image of a road with traffic lanes for a road recognized by the carriage capture unit 383, and adds the virtual image of the road to the image displayed of the front of the vehicle afterward being output to the image output unit 352.

The traffic information indicator generator 385 receives traffic information for each road obtained by the traffic information receiver 340 with respect to a point of a relevant road detected by the position determining unit 382, and loads an indicator for informing the user of traffic information for each virtual road from the storage 360.

After that, the traffic information indicator generator 385 outputs a relevant indictor for each lane of the virtual road via the image output unit 352. Furthermore, the traffic information indicator generator 385 may represent a degree of swift driving (i.e. speed) using visually distinctive characteristics (i.e. different colors, brightness, size, highlighting, etc.) of a virtual road based on the traffic information for each road and surrounding information. The surrounding information is subsequently described herein. For example, a virtual road allowing relatively high speeds may be represented using a blue color, and a virtual road requiring relatively slower driving may be represented using a red color.

The surrounding information indicator generator 386 determines surrounding information from information sensed by vehicle sensors obtained by the sensor receiver 320 and information sensed by sensors inside the terminal, and generates/loads an indicator for representing the determined surrounding information from the storage 360. The surrounding information may include a distance up to a front vehicle, a distance up to a vehicle in the sideway, etc. After that, the surrounding information indicator generator 386 outputs a relevant indicator for each virtual road via the image output unit 352. For example, an indicator representing a distance up to a front vehicle is displayed on a virtual road and/or a lane on which the vehicle is positioned, and an indicator representing a distance up to a vehicle in the sideway is displayed on a side virtual road.

The voice generator 387 loads voice regarding the traffic information and the surrounding information from the storage 360, and outputs the voice to the voice output unit 352.

More particularly, the controller 380 may control the elements to inform a relevant virtual carriageway, corresponding traffic information, and corresponding surrounding information depending on a user's eyes detected by the eyeball tracking unit 370 among a plurality of virtual roads. For example, when the user views a left road on a road image of the front of a vehicle, a virtual road for the left road, corresponding traffic information, and corresponding surrounding information are displayed.

Furthermore, the controller 380 may control the elements to inform a relevant virtual road, corresponding traffic information, and corresponding surrounding information depending on information provided by the vehicle operation information receiver 330 among a plurality of virtual roads. For example, when a left directional light flickers or a steering wheel is rotated to the left, a virtual road for the left road, corresponding traffic information, and corresponding surrounding information are added to a road image of the front of the vehicle and displayed.

In addition, the controller 380 may show only a virtual road to which the vehicle belongs from among a plurality of virtual roads, and provide traffic information and surrounding information regarding this virtual road.

In addition, the controller 380 may change a method for reporting traffic information and surrounding information depending on information provided by the vehicle operation information receiver 330. For example, when the vehicle's braking system engages to slow or stop the vehicle, an indicator representing a distance up to another vehicle directly in front or in the path of the present vehicle where the driver and terminal are positioned is displayed in relief.

As described above, the controller 380 outputs data regarding a user interface via the output unit 350 of the terminal for a vehicle. The controller 380 is not limited thereto, but may transmit data regarding the user interface to a vehicle that communicates with the terminal via a wired line or wirelessly, and the vehicle may output the user interface via a relevant output means (for example, a display), which can include audio, visual, or a combination thereof.

The controller 380 of the terminal for a vehicle according to an exemplary embodiment of the present invention may preferably include the image receiver 310, a sensor receiver 320, a vehicle information receiver 330, a traffic information receiver 340, and an eyeball tracking unit 370.
